T-lineage ALL is an aggressive disease that needs to be treated with intensive treatment schedules. A late relapse rarely occurs and a clear choice for second-line treatment is on debate. We report on a young adult with a very late isolated extramedullary relapse of PICALM-MLLT10 positive T-ALL, successfully treated with a chemotherapy-based and radiotherapy-based pediatric protocol. We demonstrate that relapse can occur in T-ALL although a SR-MRD behavior treated with a high-risk protocol; specific molecular diagnostic aberrations, as PICALM-MLLT10, are still conserved at very late relapse; a second-line treatment based on pediatric protocol can be effective.

Abstract
T-lineage ALL is an aggressive disease that needs to be treated with intensive treatment schedules. A late relapse rarely occurs and a clear choice for second-line treatment is on debate. We report on a young adult with a very late isolated extramedullary relapse of PICALM-MLLT10 positive T-ALL, successfully treated with a chemotherapy-based and radiotherapy-based pediatric protocol. We demonstrate that relapse can occur in T-ALL although a SR-MRD behavior treated with a high-risk protocol; specific molecular diagnostic aberrations, as PICALM-MLLT10, are still conserved at very late relapse; a second-line treatment based on pediatric protocol can be effective.File | Dimensione | Formato | |
